Abstract

A system and method for recovering and utilizing landfill gas for electricity generation is provided, the system comprising: a landfill, biogas collection wells configured to collect biogas in the landfill, leachate collection wells configured to collect leachate in the landfill, and carbon dioxide injection wells configured to inject carbon dioxide into the landfill. The wells are arranged in a stratification in the landfill with the one or more biogas collection wells are arranged on top of the leachate collection wells, and the leachate collection wells are arranged on top of the carbon dioxide injection wells, and the carbon dioxide injection wells being arranged at the bottom. Methane recovered from the landfill biogas is used as a fuel source in the generation of electricity and the carbon dioxide exhaust from electricity generation is injected into the landfill to enhance the extraction of the biogas.
